Geoffroy’s Wedge-Bill (Schistes Geoffroyi), John Gould This bird was first made known to us by MM. Bourcier and Mulsant in the Annals of the Royal Society of Agriculture, &c. of Lyons for 1843; fortunately for science it is one of the few species that has not received a second specific name, and hence all confusion as to its identity is obviated. This illustration has been restored to its original vibrancy by enhancing colors and removing unwanted marks. A monograph of the Trochilidæ, or family of humming-birds was published between 1849 and 1887 by English ornithologist John Gould. This monumental work depicts and describes all the known species of hummingbirds at the time - comprising 418 lithographic plates and information on 537 species."
